NC Secretary of State. Or provide a signed letter from one of the member/managers
listed giving Cedric Combo signature authority. Not in the most recent submittal.
DPR Response: The revised signed/notarized O&M and Deed Restriction are
included with submittal package.
2. Repeat comment: The notary mistakenly signed in the space where the applicant and
property owner are supposed to sign. Please provide a corrected signed original of
SWU‐101, O&M agreement, and the deed restrictions. Not in the most recent submittal
DPR Response: The revised signed/notarized O&M, SWU‐101 and Deed Restriction
forms are included with submittal package.
3. Repeat comment: Revise SWU‐101 Sect. IV.10: Provide the BUA breakdowns for each DA
in the bottom table. These were left blank. Not in the most recent submittal
DPR Response: Done.
4. The plans provided are not printed to scale (Sht. L‐3 through L‐8, and L‐19).
DPR Response: Done.
5. The design calcs for sand filter 1 are not consistent with the plans or DA breakdown
calcs. DA and BUA shown as 5 vs. 4.5 and 2.4 vs. 2.16, respectively. Note that for sand
filters, you may choose to use 75% of the WQV per the MDC.
DPR Response: The plans, DA breakdown and BUA are consistent with each other.
The proposed sand filters were overdesigned to treat 100% of the water quality
volume to compensate for the untreated runoff at the proposed road improvement
for existing Faith Road.
Revise the supplement forms:
a. All sand filters: still a few items were left blank (el. of bypass, desc. of bypass,
flow dist., ponding depth from sf top to bypass).
DPR Response: This was corrected
b. Sand filter 1: the design volume minimum and provided are not consistent with
the plans and calcs.
DPR Response: This was corrected.
